Corpus bursae two and a half times longer than ductus bursae and wider at junction with ductus bursae. Geographical distribution . Only known from the type locality at higher elevations ( 1900 m ) in the Mantiqueira Mountains of eastern São Paulo state ( Figs 58 , 60 ) . Host plants . Unknown. Etymology . The proposed specific name alludes to the high altitude where this species occurs. It is treated as an adjective in the nominative singular.
